US Energy & Utilities Software: a $1.3B market at a turning point

The US energy software landscape is undergoing a fundamental shift. Historically dominated by robust but legacy systems designed for vertically integrated, regulated monopolies, the market is now being reshaped by deregulation, new entrants, and increasing demand for agile, cloud-native platforms.

This article focuses specifically on the retail electricity software segment, a subset of the broader energy & utilities software market. While the entire space is significantly larger, our research zeroes in on CIS (Customer Information Systems), billing, and EDI platforms used by electricity retailers and utilities, which represents a $1.3B Total Addressable Market (TAM).

‍

A massive, fragmented and consolidating market

The US electricity sector operates under a dual market structure:

• Regulated markets (33 states): Electricity providers manage the full value chain from generation to distribution. These are regional monopolies whose prices and investments are overseen by Public Utility Commissions (PUCs).

• Deregulated markets (17 states + D.C.): Generation and retail are open to competition. End customers can choose their electricity supplier, while utilities still manage the grid infrastructure.

‍

This results in two distinct software profiles:

• Utilities (regulated): demand highly secure, infrastructure-grade systems with deep grid integration.

• Retailers (deregulated): focus on pricing intelligence, customer engagement, and SaaS-based agility.

‍

Despite the complexity, the CIS + billing + EDI software market alone accounts for $1.3B TAM, with a $0.8B SAM primarily made up of Investor-Owned Utilities (IOUs), a segment that represents 52% of the addressable market.

Importantly, the market is consolidating, particularly among utilities. Fewer large accounts and increasingly standardized tech stacks make vendor penetration more scalable for software providers and more attractive for investors.

Different players, different needs

Regulated utilities:

• Operate under long, CAPEX-driven cycles (15+ years for software replacement), with regulatory approval required.

• Favor platforms like SAP and Oracle.

Key priorities:

• Integration with grid operations

• Compliance (SOC1, SOC2, ISO27001)

• Billing accuracy and scalability

‍

Retail Energy Suppliers:

• Operate in competitive markets, often as lean, growth-driven players.

• Replace software every 3–5 years.

• Adopt modern, SaaS-native platforms.

Key priorities:

• Flexible pricing and bundling

• Customer engagement and retention tools

• Fast implementation and low overhead

‍

Market dynamics and emerging plays

Several structural shifts are shaping the vendor landscape:

• Consolidation among utilities is reducing the number of large accounts but increasing solution standardization, a positive signal for scalability and investment.

• Retailers are internalizing CIS functions to improve control over margin and customer experience.

• Off-the-shelf adoption is growing, especially among Tier 2 and Tier 3 players who seek speed and flexibility.

• Foreign challengers such as Kraken and Kaluza (after disrupting the UK) are entering the US market with AI-driven, cloud-native solutions.

• While SAP and Oracle still dominate Tier 1 accounts, their stronghold is being challenged by more modern, cost-effective vendors.

Strategic takeaways

For software providers:

Segment-focused strategies are critical. Utilities will continue to value stability, integration, and compliance. Retailers expect flexibility, SaaS delivery, and fast ROI.

‍

For investors:

The space combines defensive characteristics (sticky clients, long replacement cycles) with growth triggers (deregulation, modernization, vendor churn). Consolidation adds further appeal for buy-and-build or scale strategies.

‍

For utilities and retailers:

The real opportunity lies in upgrading from billing systems to full customer intelligence platforms, integrating smart metering, AI-based pricing, and omnichannel service to stay competitive.

‍

The US energy software market sits at the intersection of infrastructure-grade stability and market-driven innovation. While $1.3B reflects the retail software niche we focused on, the broader transformation of energy IT stacks is far more extensive and ongoing.

At Dedale, we believe this market remains largely untapped, especially for vendors and investors able to bridge the legacy-modernization gap and navigate the unique duality of US energy regulation.
